Seriously tempted to do an alphabet...
Bit of a glass study.
It does look quite glassy now that you mention it... An entire font of this would be intense, I'd end up using it quite a bit.
12? No life :V
Might make all 26, but put together in one piece. Might make another wasp to go behind, they rarely hang 'round solo :P
Glass is tough. It really depends on what's around it that reflects/distorts into it. And what you have is curved glass which is even more difficult.
This looks shiny but not so glassy. It's beyond me so I can't offer any advice aside from agreeing with skamocore. Love the yellow jacket though.
Maybe you should do the whole alphabet. You know some idiot entered a weekly challenge 12 times, maybe you could beat his score by doing 26 entries o:
Also, it looks good, but not entirely sure that it comes off as being that glassy. Maybe have a look at some images of test tubes (if you haven't already). Hard mode: you could place the yellow jacket behind a part of the Y and show how his appearance distorts as a result of being viewed through glass.
